Display switching device, switch, and electrical apparatus

A display switching device, switching a display image by switching irradiation of light from a plurality of light sources, the display switching device comprising:

• a lens array, in which a plurality of lenses are arranged;
• and
• a display part,
• wherein the display part comprises a plurality of pixel regions, the pixel regions being disposed to comprise regions through which light condensed by each of the lenses of the lens array passes,
• a transmittance in each of the pixel regions is set to correspond to a predetermined static pattern, and
• in at least a portion of the lens array, a mean plane of a light incident surface and a mean plane of a light exit surface are curved surfaces, and (1) the curved surface of the mean plane of the light incident surface is concave, and the curved surface of the mean plane of the light exit surface is convex, or (2) the curved surface of the mean plane of the light incident surface is convex, and the curved surface of the mean plane of the light exit surface is concave.
